Tidsramme |
|---|---|---|
|
Change in Interleukin-6 (Value at Week 8 Minus Value at Week 0)
Tidsramme: 8 weeks
|
Plasma samples collected from participants at the beginning (week 0) and end of the study (week 8) will be analyzed for interleukin-6 concentrations using an enzyme linked immunosorbent assay.
Changes in the concentrations of these inflammatory markers will be determined from week 0 to week 8.

Change in Tumor Necrosis Factor-α (Value at Week 8 Minus Value at Week 0)
Tidsramme: 8 weeks
|
Plasma samples collected from participants at the beginning (week 0) and end of the study (week 8) will be analyzed for tumor necrosis factor-α concentrations using an enzyme linked immunosorbent assay.
Changes in the concentrations of these inflammatory markers will be determined from week 0 to week 8.

Change in High Sensitivity C-reactive Protein (Value at Week 8 Minus Value at Week 0)
Tidsramme: 8 weeks
|
Plasma samples collected from participants at the beginning (week 0) and end of the study (week 8) will be analyzed for high sensitivity C-reactive protein concentrations using an enzyme linked immunosorbent assay.
Changes in the concentrations of these inflammatory markers will be determined from week 0 to week 8.

Change in Lipopolysaccharide Binding Protein (Value at Week 8 Minus Value at Week 0)
Tidsramme: 8 weeks
|
Plasma samples collected from participants at the beginning (week 0) and end of the study (week 8) will be analyzed for lipopolysaccharide binding protein concentrations using an enzyme linked immunosorbent assay.
Changes in the concentrations of these inflammatory markers will be determined from week 0 to week 8.

Change in Gut Microbiota Shannon's Alpha Diversity (Value at Week 8 Minus Value at Week 0)
Tidsramme: 8 weeks
|
The Shannon Diversity Index is a quantitative measure that reflects how many different bacterial species there are in a sample.
The greater the index, the more diverse the gut microbiota.
A negative change indicates a decrease in diversity and a positive change indicates an increase in diversity.

Change in Fecal Short Chain Fatty Acids (Value at Week 8 Minus Value at Week 0)
Tidsramme: 8 weeks
|
Short-chain fatty acids (SCFAs) are the end products of fermentation of dietary fibers by the anaerobic intestinal microbiota.
SCFAs have been shown to exert multiple beneficial effects on mammalian energy metabolism.
|
8 weeks
|
|
Change in Branched Chain Fatty Acids (Value at Week 8 Minus Value at Week 0)
Tidsramme: 8 weeks
|
Branched chain fatty acids (BCFA) are mostly saturated fatty acids (SFA) with one or more methyl branches on the carbon chain.
BCFAs were extracted from stool samples and measured using gas chromatography.
